Thomas, Wales' record try-scorer, will complete his move from the Celtic Warriors and is the latest member of Wales' 2003 World Cup squad to play in France next season, after Stephen Jones (Montferrand) and Colin Charvis (Tarbes).

Before then, Thomas will be in action for Wales, lining up against the Barbarians at Ashton Gate tonight.

Gloucester have agreed to release Argentinian prop Rodrigo Roncero from his contract.

Roncero, 27, joined Gloucester in September 2002 and has made 22 Zurich Premiership appearances.

Roncero, a fully qualified doctor, intends to return to his home city of Buenos Aires.

Meanwhile, Simon Amor has agreed a new two-year contract.

Amor, who is also captain of the England Sevens team, has made 10 Zurich Premiership appearances this season.

Bath have received a triple fitness boost ahead of Saturday's Zurich Premiership final against Wasps at Twickenham.

England internationals Mike Tindall, Mike Catt and Matt Perry have all been declared fit for the game although prop David Flatman is likely to be ruled out.

Flatman's Achilles' tendon injury has sidelined him for the final and also England's tour to New Zealand and Australia next month.

The England management team have not yet made an official announcement, but it is understood that Flatman has little chance of making the three-Test trip.

Bath are set to replace him against European champions Wasps with either Matt Stevens or David Barnes.

Centre Tindall has not played for almost two months, initially because of a stomach muscle injury, and then a hamstring problem suffered in training.

But he has been given the all-clear to feature this weekend, with Catt and Perry also in contention following recent injury troubles.
